The cytoplasmic domain of the cell adhesion molecule uvomorulin associates with three independent proteins, named catenins, which are structurally related in different cell types of various species. This complex formation connects uvnomorulin and cytoskeletal structures and might, moreover, be involved in other adhesion‐dependent mechanisms.

In 1981, Takeuti introduced quantum set theory as the quantum counterpart of Boolean valued models of set theory by constructing a model of set theory based on quantum logic represented by the lattice of closed subspaces in a Hilbert space and showed that appropriate quantum counterparts of ZFC axioms hold in the model. Here, Takeuti's formulation is extended to construct a model of set theory based on the logic represented by the lattice of projections in an arbitrary von Neumann algebra. (...) A transfer principle is established that enables us to transfer theorems of ZFC to their quantum counterparts holding in the model. The set of real numbers in the model is shown to be in one-to-one correspondence with the set of self-adjoint operators affiliated with the von Neumann algebra generated by the logic. Despite the difficulty pointed out by Takeuti that equality axioms do not generally hold in quantum set theory, it is shown that equality axioms hold for any real numbers in the model. It is also shown that any observational proposition in quantum mechanics can be represented by a corresponding statement for real numbers in the model with the truth value consistent with the standard formulation of quantum mechanics, and that the equality relation between two real numbers in the model is equivalent with the notion of perfect correlation between corresponding observables (self-adjoint operators) in quantum mechanics. The paper is concluded with some remarks on the relevance to quantum set theory of the choice of the implication connective in quantum logic. (shrink)

The recently established universal uncertainty principle revealed that two nowhere commuting observables can be measured simultaneously in some state, whereas they have no joint probability distribution in any state. Thus, one measuring apparatus can simultaneously measure two observables that have no simultaneous reality. In order to reconcile this discrepancy, an approach based on quantum logic is proposed to establish the relation between quantum reality and measurement. We provide a language speaking of values of observables independent of measurement based on quantum (...) logic and we construct in this language the state-dependent notions of joint determinateness, value identity, and simultaneous measurability. This naturally provides a contextual interpretation, in which we can safely claim such a statement that one measuring apparatus measures one observable in one context and simultaneously it measures another nowhere commuting observable in another incompatible context.

The emotions that people experience in day-to-day social situations are often mixed emotions. Although autobiographical recall is useful as an emotion induction procedure, it often involves recalling memories associated with a specific discrete emotion. However, real-life emotions occur freely and spontaneously, without such constraints. To understand real-life emotions, the present study examined characteristics of emotions that were elicited by recalling “stressful interpersonal events in daily life” without the targeted evocation of a specific discrete emotion. Assuming generation of mixed and complex (...) emotions, emotional groups with relatively strong correlation of multiple emotions according to surprise, fear, anger, disgust, sadness, and happiness were expected. Seventy-two university students participated in the study. In the emotion induction procedure, participants freely recalled memories as per the instructions on a monitor, and then responded silently to a series of questions concerning any one recalled incident. Assessments of emotional states using emotion scales and another item indicated that validated emotional changes had occurred during the task. Inter-correlations between six emotions demonstrated an emotional group consisting of disgust and anger, which frequently occur as negative interpersonal feelings, and that of fear and sadness. This indicated generation of mixed and complex emotions as experienced in social life. Future studies concerning relationships between these emotions and other factors, including neurophysiological responses, may facilitate further understanding about relationships between mental and physiological processes occurring in daily life.

Western sociology of the body, despite its attempt to create a somatic approach to human existence, inevitably shares many of the rationalistic and Cartesian assumptions of wider Western sociology. A contrasting, and in many ways radically different approach is that found in both classical and contemporary Japanese thought. In this article two major contemporary Japanese theorists of the body - Ichikawa Hiroshi and Yuasa Yasuo - are introduced and their work examined as distinctive, and in the West virtually unknown, contributions (...) to body analysis. Their views are briefly contrasted with some of the major themes of Western, and in particular British, sociology of the body and the implications of their work for future investigation of the human body are sketched out.

A nonstandard universe is constructed from a superstructure in a Boolean-valued model of set theory. This provides a new framework of nonstandard analysis with which methods of forcing are incorporated naturally. Various new principles in this framework are provided together with the following applications: An example of an 1-saturated Boolean ultrapower of the real number field which is not Scott complete is constructed. Infinitesimal analysis based on the generic extension of the hyperreal numbers is provided, and the hull completeness theorem (...) and the Loeb measure construction are extended to objects in the generic extension of the internal universe. The reduction theory of the Boolean-valued complex numbers are developed as a prototype of the applications to the topological reduction theory of Boolean sheaves or operator algebras. (shrink)

In quantum logic, introduced by Birkhoff and von Neumann, De Morgan's Laws play an important role in the projection-valued truth value assignment of observational propositions in quantum mechanics. Takeuti's quantum set theory extends this assignment to all the set-theoretical statements on the universe of quantum sets. However, Takeuti's quantum set theory has a problem in that De Morgan's Laws do not hold between universal and existential bounded quantifiers. Here, we solve this problem by introducing a new truth value assignment for (...) bounded quantifiers that satisfies De Morgan's Laws. To justify the new assignment, we prove the Transfer Principle, showing that this assignment of a truth value to every bounded ZFC theorem has a lower bound determined by the commutator, a projection-valued degree of commutativity, of constants in the formula. We study the most general class of truth value assignments and obtain necessary and sufficient conditions for them to satisfy the Transfer Principle, to satisfy De Morgan's Laws, and to satisfy both. For the class of assignments with polynomially definable logical operations, we determine exactly 36 assignments that satisfy the Transfer Principle and exactly 6 assignments that satisfy both the Transfer Principle and De Morgan's Laws.

The model of mind and body in Tibetan medical practice is based on Buddhist theory, and is neither dualistic in a Cartesian sense, nor monistic. Rather, it represents a genuine alternative to these positions by presenting mind/body interaction as a dynamic process that is situated within the context of the individual’s relationships with others and the environment. Due to the distinctiveness, yet interdependence, of mind and body, the physician’s task is to heal the patient’s mind (blo-gso) as well as body. (...) This in turn emphasizes the central importance of ‘compassion’ in the physician/patient relationship. This article investigates how Tibetan medical practitioners understand and enact the mind/ body and physician/patient relationships, and how this relates to theoretical explications of these relationships in Tibetan medical and Buddhist teachings. Furthermore, Tibetan medicine provides an interesting model for comparison with embodied theories of cognition, which see consciousness, the body and its environment as integral parts of a complex, dynamical cognitive system.

An ordered field is said to be Scott complete iff it is complete with respect to its uniform structure. Zakon has asked whether nonstandard real lines are Scott complete. We prove in ZFC that for any complete Boolean algebra B which is not (ω, 2)-distributive there is an ultrafilter U of B such that the Boolean ultrapower of the real line modulo U is not Scott complete. We also show how forcing in set theory gives rise to examples of Boolean (...) ultrapowers of the real line which are not Scott complete. (shrink)

Long time delay before lasing in a II-VI laser diode has been observed. Due to this delay, a nominal threshold current increases as the width of applied current pulse becomes shorter. This delay is attributed to the internal Q switching caused by the balance of injected carriers, temperature rise and gain-guiding. By fitting the calculated data to the experimental ones, rates of refractive index change with carrier concentration and with temperature have been estimated.

Involuntary eye movement during gaze fixation, referred to as fixational eye movement, consists of two types of components: a Brownian motion like component called drifts-tremor and a ballistic component called microsaccade with a mean saccadic amplitude of about 0.3° and a mean inter-MS interval of about 0.5 s. During GZ fixation in healthy people in an eccentric position, typically with an eccentricity more than 30°, eyes exhibit oscillatory movements alternating between centripetal drift and centrifugal saccade with a mean saccadic amplitude (...) of about 1° and a period in the range of 0.5–1.0 s, which has been known as the physiological gaze-evoked nystagmus. Here, we designed a simple experimental paradigm of GZ fixation on a target shifted horizontally from the front-facing position with fewer eccentricities. We found a clear tendency of centripetal DRT and centrifugal MS as in GEN, but with more stochasticity and with slower drift velocity compared to GEN, even during FEM at GZ positions with small eccentricities. Our results showed that the target shift-dependent balance between DRT and MS achieves the GZ bounded around each of the given targets. In other words, GZ relaxes slowly with the centripetal DRT toward the front-facing position during inter-MS intervals, as if there always exists a quasi-stable equilibrium posture in the front-facing position, and MS actions pull GZ intermittently back to the target position in the opposite direction to DRT.

Generalizing a result of Todorčević, we prove the existence of directed sets D, E such that D ≱ [MATHEMATICAL SCRIPT CAPITAL P]κλ and E ≱ [MATHEMATICAL SCRIPT CAPITAL P]κλ but D × E ≥ [MATHEMATICAL SCRIPT CAPITAL P]κλ in the Tukey ordering. As an application, we show that the tree property for directed sets introduced by Hinnion is not preserved under products.

The recognition and extraction of semantic/logical structures in HTML documents are substantially important and difficult tasks for intelligent document processing. In this paper, we show that the alignment technology is an appropriate tool, within a framework of case-based reasoning, for recognizing semantic structures inherently embedded in a series of HTML documents. That is, given a series of HTML documents and a document example of which semantic structures are explicitly indicated by a user, then the alignment can identify semantic structures in (...) the HTML document series, by matching a text-block sequence in each HTML document with the text-block sequence in the example document. Several important properties in text documents, such as continuity, sequentiality of texts, can be treated by the alignment in a quite natural way. The alignment technology can significantly improve the capability of the case-based transformation method which transforms a spatial and/or temporal series of HTML documents into machine-readable XML formats. Moreover, the alignment dramatically eases the construction of transformation exmaples. Throughout experimental evaluation for 47 pages of 8 series of HTML documents, we show that the case-based method using the alignment achieved a highly accurate transformation into XML formats.

All surviving jawed vertebrate representatives achieve diversity in immunoglobulin‐based B and T cell receptors for antigen recognition through recombinatorial rearrangement of V(D)J segments. However, the extant jawless vertebrates, lampreys and hagfish, instead generate three types of variable lymphocyte receptors (VLRs) through a template‐mediated combinatorial assembly of different leucine‐rich repeat (LRR) sequences. The clonally diverse VLRB receptors are expressed by B‐like lymphocytes, while the VLRA and VLRC receptors are expressed by lymphocyte lineages that resemble αβ and γδ T lymphocytes, respectively. These (...) findings suggest that three basic types of lymphocytes, one B‐like and two T‐like, are an essential feature of vertebrate adaptive immunity. Around 500 million years ago, a common ancestor of jawed and jawless vertebrates evolved a genetic program for the development of prototypic lymphoid cells as a foundation for an adaptive immune system. This acquisition preceded the convergent evolution of alternative types of clonally diverse receptors for antigens in all vertebrates, as reviewed in this article. (shrink)

西元前256年，周赧王被秦昭襄王所征服。由此，戰國時代最後階段的華夏世界進入三十五年的「後周魯時代」。 本書提出：在此時期周天子不在的政治權威空白時期，實為《荀子》和《呂氏春秋》兩書之出現的主要契機。以這樣歷史背景為主要契機誕生的兩書，其政治哲學的目標便應該在於構想能治理全天下人民之國家的建立──《荀子 》探求未來以禮義治理天下的君王；《呂氏春秋》則向已成為「de facto天子」的秦王，為提升至名正言順的天子，提供政策綱要和實踐細則。 作者根據較為嚴謹的「觀念史／概念史」分析，闡述《荀》、《呂》兩書在思維上、概念上、論述內容上等多層次的思想特質及其歷史角色。期盼本書在戰國秦漢時代的歷史和思想相關議題之探討能夠提供較新的切入點，並擴大 研究視野。.

Cultures are constituted by binary oppositions: the absolute and the relative; the perfect and the imperfect; the stable and the unstable. Many of the world’s cultures have looked to revealed religion to discover the absolute: that which transcends the human, the intellect, and space and time. By positing a God who is omniscient and omnipotent, they conceive of an eternal and absolute that continues to exist in an immutable state.In such cultures new perspectives for reinterpreting the past are continually propounded. (...) This allows history to be rewritten and re-rewritten. History simply becomes a method for becoming conscious of the past.By contrast, many East Asian cultures have not developed such a concept of revealed religion. For them, history itself constitutes an absolute, something on which one can rely. History in East Asia is endowed with a normative function, a source of authority that does not permit easy rewriting. (shrink)

本書構畫「忠」概念在中國春秋戰國時代的演變，並嘗試藉此闡明其功能與特質。在春秋到戰國早期的政治思想中，「忠」和「忠信」概念對於國家社稷的生存幾乎是最高價值，而且到戰國中期更具有涵蓋「天下」的普遍性。然 而在戰國中期以後，道家與稷下思想家如慎到等人開始批判「忠」的價值，並且將原本以道德動機為主要內涵的「忠」概念、轉變成以個人利益為主要實踐動機的「忠」概念。面對此趨勢，戰國晚期的《荀子》和《呂氏春秋》都 試圖重新界定「忠」對國家運作的正面價值，而《韓非子》雖然基本上接受稷下學者之「反忠論」，但還是肯定「忠臣」是國家社稷安定的關鍵角色。本書也對中日韓及歐美學者過去研究「忠」概念的成果有詳細評述。.
